Aug. 21, 1934. E. G. HALLQU|S' RAILWAY JOURNAL BOX AND ASSOCIATEDSTRUCTURE Filed June 13', 1932 4 Sheets-Sheet 4 Patented Aug. 21, 1934UNITED STATES 1.911.004 mmwsr .Iomu m. sox m assocm'rm 'I'BUCTUBEinarGJhllquist, some, 111.,aaslgnorto General Steel CastingsGeneration, Granite 18-Claims.- (cl. 105-218) The invention relates torailway rolling stock and consists in a novel assembly of the frame andjournal boxes of a railway vehicle.

In the usual construction, Journal boxes are slidably mounted inpedestals either in the vehicle underframe or in the truck frame. Thepedestals have'elongated bearing surfaces for engaging the boxes and.require machining, and

are usually provided with liners or other'wearing 10 elements. Thelongitudinal forces resulting from draft, buiiing, and application ofbrakes are transmitted between the wheels and the truck or frame throughthese pedestals. In

' locomotives there is a similar longitudinal force 18 resulting fromthe piston and connecting rod thrusts.

Hence, the pedestal and box structure must be heavy enough to withstandthese forces and the wear due to the sliding movements, and as l aresult the pedestals comprise a large portion of the material of thevehicle underframe or truck.

The main object of the present invention is to anchor the boxes to theunderframe or truck by a linkage device which will transmit the forcesusually transmitted through the pedestals and thereby eliminate thepedestals and simplify the construction of the vehicle and reduce itsweight and cost of manufacture;

Another object of the invention is to provide a linkage as describedwhereby relative longitudinal or transverse" movement of the boxes inthe underframe or truck frame is prevented although the boxes are leftfree to move verti- 35 cally in order for the springs carried thereby tofunction. i j

Another object of the invention is to eliminate the sliding bearings ofpedestals and boxes thereby avoiding lost motion, due to wear, and

the necessity of replacing wearing elements at intervals.

In the accompanying drawingsthe invention is illustrated as applied to alocomotive underframe and the driver boxes assembled therewith as theproblems of weight, wearing surfaces, machining, lost motion, and'otherobjectionable features of the ordinary pedestal and box arrangement arepresent to a striking degreein a locomotive. It is to be understood,however, that the invention may be applied to any railway. vehicleJournal box arrangement whether the box is assembled with the vehicleunderframe or with a vehicle truck frame upon which the underframe ismounted.

Figure 14; is a diagrammatic view illustrating the action of the linkagedevices.

The vehicle underframe is illustrated as a one-piece cast structurehaving a box-like body member with top and bottom walls 1 and 2 and sidewalls 3. At the sides of the body member are outwardly and downwardlyprojecting brackets 4 disposed in the same general plane as the Journalboxes 5. These boxes are mounted upon the journals 6 of the axles 7 inthe usual manner and preferably each box has an integral upstandingspring saddle 8 carrying a spring 9 from the ends of which hangers 10depend and support the equalizers 11 fulcrumed at 12 on brackets 4 toform a continuous spring equalizing system as is in general use.

The upper portion of each box includes a pair of spaced bearings 13 forpivotally mounting one end of a substantially horizontal link 14 whichextends across the top of the box through the spring saddle 8 andthrough the bifurcated hanger 10 and has its opposite end pivoted to abracket 4, as indicated at 15.

The lower portion of the box diagonally opposite bearings 13 includes abifurcated arm 16 having a pair of bearings 17 for'pivotally mountingone end 0! a link 18 which extends across the lower portion of the boxand has its Opposite end pivotaily connected to the lower portion of thebracket 4 on the opposite side of the box, as

- the locomotive.

The linkage arrangement described comprises .an embodiment ofWattsstraight line motion move up and down relative to the vehicleframe,

permitting the spring suspension means to -function, and the piston orconnecting rod thrust may be transmitted to the frame through the pins15, 19, 20 and 21 without any sliding en= gagement of the. box andframe. A similar transverse linkage'device is best illustrated inFigures 4 and 7; 'I'hisstructure includes an inverted U-shaped spacer 22straddling the axle 7 with its ends abutting the inner surfaces ofjournal boxes 5 onopposite sides of 'One or more vertical links 23 arepivoted'at 24 intermediate their ends to spacer 22, and'horizontal links25 and 26 have corresponding ends pivoted to the upper and lower ends oflinks 23, respectively,.and have their opposite ends pivoted to theunderframe'at 27 and 28, respectively. Qbviously the linkage justdescribed provides relative vertical movement of the box, axle, andframe but prevents relativemovement of the axle, wheels and boxestransversely of the frame. The vertical movement accommodates tilting ofthe axle and boxes as results when one wheel is at a low point in thetrack, and the'other wheel is at a relatively high point. .The lateralthrusts of thewheels aretransmitted through the wheel hubs to the boxesand from the latter through the spacer and linkage device to the frame.This e the usual bearing elementson the opposed fac of the pedestals anddriving boxes.

The box-shaped body member carries the em tire longitudinal forces dueto the piston t, application of brakes, and other longital bufiing andpulling stresses. The brackets s in cluding the pivot bearings for linksis and i8,

the bearings for the equalized fulcrum pins 12,

and the bearings 29for brake hanger lug pins preferably are integralwith each other and with the central body member and this arrangementprovides a simple cast bed structure having a minimum weight for thedesired capacity.

The modification illustrated in Figures 8 to 13 includes amain framebody member with top and bottom walls 30 and 31, and side walls 32corresponding generally to the body member previously described,Continuous supplemental members are provided at each side of the bodymember and comprise spaced vertical webs 33 and 34 which extend over thejournal boxes 35, and the spring saddle 36, on the journal box projectsupwardly. between webs 33 and 3d. The box 35 is arranged foranti-friction bearings 37 in place of the usual brass indicated inFigures 2 and 4. Horizontal webs 38 and 39 extendbe tween vertical webs33 and 34 and form therewith a box-shaped side member which cooperateswith the central body member in transmitting longitudinal forces.

The bearings 40 and 41 for the box links and the bearings 42 for theequalizer fulcrums are formedintegral with webs 33 and 34 and with thisarrangement there are no eccentric forces transmitted through thevertical webs 33 and 34. r

The transverse linkage (Figures 10, 12, i3) is applied to the axle bymeans of a two-part ormer.-

collar 43 surrounding axle 4e and held in place thereon by the axleflanges45. The upright links 46 are pivoted at 4'? to collar 43 and areconnected to the frame as are the corresponding links previouslydescribed. This arrangement transmits thelateral thrust of the axlesdirectly tothe linkage through flanges 45 instead of through the wheelhub, the driving box and atransverse housing as previously described;

With each of the structures illustrated and described the longitudinaland transverse spacing of the wheels relative to each other and to themain frame is maintained irrespective of variations in the height of thedifferent wheels. This desirable constant is obtained without anyexcessive play being required between the link pins and their bearingsand without any abnormal straining of the parts. Various box and bodylinking arrangements have been suggested heretofore, but so far as I amaware, such arrangements produced movement of the boxes in arcs aboutthe link pivots when the wheels moved vertically due to irregularitiesin rails, orfor other reasons, and this has required undesirable playand/or wear in the .various partsconnected by the links.

While the invention is illustrated as embodied in a railway steamlocomotive, it is to be unbodied in other types of locomotive vehiclesand in vehicle trucks which maybe pivoted to the vehicle underframe bymeans of the usual center pin arrangement. I- contemplate the exclusiveuse of my invention irrespective of modifications in design and detailswhich may be required for its adaptation to different vehicleunderframing or truck framing but coming within the spirit of my claims.
